Hi, i'm trying to use serial port with matlab. This is the code that i've used:
s1 = serial('COM14');
set(s1,'BaudRate',9600);
fopen(s1)
This is the message of Matlab:
Cannot connect to the COM14 port. Possible reasons are another application is connected to the port or the port does not exist.
The port is connected because Matlab says:
Available ports: COM3, COM9, COM14, COM16.
With HyperTerminal i can open and use the PORT14. What's is wrong? Thank you for your attention.
